C Resources

  

All the GUI visualisation tools define a number of resources which control the appearance and functionality of the tools. Many of these resources are common to other non-visualisation programmes for the X Window system, such as the <xterm> programme. Listed below are those resources which are specific to Karma visualisation tools. These resources may be set in your /.Xdefaults file, which is the standard file into which to put your personal resources. Some systems use the non-standard /.Xresources file instead, although the format is the same. On SGI systems you may need to put your Karma resources in a separate file and run:
xrdb -merge <filename>
in your window system startup script. You may also/instead (on SGI systems) need to set resources in your /.Sgiresources file.

In some cases you will need to prepend the application classname (i.e. Kvis) to the resource name. First try specifying the particular resource as shown and if that doesn't work prepend the application classname.

• *ZoomPolicy.fixAspect this controls whether the aspect ratio will be fixed (True) or not (False)
• *ZoomPolicy*integerXZoomToggle.state this controls whether horizontal zooming will be forced to integer multiples (True) or not (False)
• *ZoomPolicy*integerYZoomToggle.state this controls whether vertical zooming will be forced to integer multiples (True) or not (False)
• *IntensityPolicy*resetIntensityToggle.state this controls whether the intensity range will be reset upon loading of a new file (True) or not (False)
• *iscaleMenu*setChoice this controls the default intensity transformation. The folowing are supported:
  • linear the screen intensity is proportional to the input data values
  • log(val-min) the screen intensity is proportional to the logarithm of the input data values
  • log(max-val) the screen intensity is proportional to the logarithm of the negative input data values
  • sqrt(val-min) the screen intensity is proportional to the square root of the input data values
• *MagnifierPopup.fastPanner this controls whether the magnifier window will use a fast, large-memory mode (True) or not (False) panner. The default is to use the slower, small-memory panner. In most cases the default mode is quite fast enough, unless you enlarge the magnifier window so it nearly fills your screen. The reason the default is to use the small-memory mode is that if you have a large image (say 2k*2k) then the fast mode would require 64 MBytes of RAM just to store one copy of the image! Unless you have lots of RAM in your computer, you will be forced to wait a long time while your machine swaps to disc, hence the default
• *ImageDisplay.fastPanner as above, but applies to the main image window. The default is to use the fast, large-memory panner. This is only of significance when you use panning mode (i.e. select ``Panner'' from the ``Zoom'' menu)
• *MagnifierPopup.showCrosshair this controls whether magnifier windows should show a crosshair (True) or not ( False)
• *displayAxisLabelsToggle.state if this is True then most windows which support axis labels will have enabled them by default. You also need to set the *OverlayMenu.createAtInit resource to True (see below)
• *OverlayMenu.createAtInit if this is True then creation of certain control panels is performed at programme startup, rather than being delayed until if (and when) required. Normally, delayed creation is preferred, since it speeds application startup, but this prevents some resource specifications from taking effect until sometime later. Some programmes provide the shorthand `` -create_at_init'' option
• *transient if True all popup windows will be iconified if the main window is iconified
• *AnimateControl*pinToggle.state this controls whether the animation control will be stay popped up when an image is displayed (True) or will be popped down (False)
• *AnimateControl.transient as above but specifically only for the AnimateControl widget (section 2.3)
• *Cmapwinpopup.transient as above for the Cmapwinpopup widget (section 2.2)
• *Dataclip.transient as above for the Dataclip widget (section 2.2)
• *Dataclip*subsetToggle.state this controls whether a subset of the input data will be used to compute a histogram for the Dataclip widget (section 2.2)
• *Dialogpopup.transient as above for the Dialogpopup widget
• *DressingControl.transient as above for the DressingControl widget (section 2.8)
• *Filepopup.transient as above for the Filepopup widget (section 2.1)
• *Filepopup*dotsToggle.state control whether (True) or not (False) hidden files and directories are shown by default in the Filepopup widget (section 2.1)
• *Filewin.numLines the desired size of the directory browser (in lines). The default is that the browser size is automatically configured
• *Filewin*list.translations may be used to change the file browser mouse behaviour. The default is to highlight the entry under the current mouse pointer position. If you specify <Btn1Down>:Set()n<Btn1Up>:Notify() then highlighting only occurs when an entry has been selected. The only advantage of this behaviour is that it leaves the last selected entry highlighted (i.e. moving the mouse won't highlight a different entry)
• *IntensityPolicy.transient as above for the IntensityPolicy widget (section 2.2)
• *LoadAndDecimate.transient as above for the LoadAndDecimate widget (section 2.1.1)
• *MagnifierPopup.transient as above for the MagnifierPopup widget (section 2.9)
• *MomentGenerator.transient as above for the MomentGenerator widget (section 2.16)
• *OverlayEditorControl.transient as above for the OverlayEditorControl widget (section 2.19)
• *PannerPopup.transient as above for the PannerPopup widget (section 2.10)
• *Postscript.transient as above for the Postscript widget (section 2.4)
• *SlaveImageDisplayPopup.transient as above for the SlaveImageDisplayPopup widget
• *TracePopup.transient as above for the TracePopup widget (section 2.11)
• *View2Datasets.transient as above for the View2Datasets widget (section 4)
• *ZoomPolicy.transient as above for the ZoomPolicy widget (section 2.7)
• Kvis.geometry the size and placement of the main display window for <kvis>. The default is +0+0 (top left)
• Kvis*firstDataBrowserShell.geometry the size and placement of the first data browser window for <kvis>. The default is +540-0 (to the right of the main display window and at the bottom of the screen)
• Kvis*imageDisplayShell1.geometry the size and placement of the second display window for <kvis>. The default is -0+0 (top right)
• *Postscript*nameDialog*font the name of the font to use in the text-entry dialog for the output filename in the Postscript widget (section 2.4)
